A device for improving the quality of biological feed

technical field

The utility model belongs to the technical field of biological feed, in particular to a device for improving the quality of biological feed.

Background technique

Biological feed is a feed product that is produced by solid-state fermentation after the feed raw materials are inoculated with microbial liquid and mixed evenly.

In the production of biological feed, when the powdered feed material and the liquid microbial solution are inoculated and mixed in the mixing equipment, due to the high water content of the material, it is easy to agglomerate. After the material is agglomerated, the interior of the agglomerated material is not fully mixed with the microbial solution Uniformity, even if the middle part of the agglomerate material is not in contact with the microbial liquid, if such agglomerate material is not broken up and mixed evenly, it will not be fermented completely during the solid-state fermentation stage, causing the agglomerate material to be "cooked raw material", making biological feed The quality is not high, which seriously affects the use.

In order to obtain high-quality biological feed products, a device that can avoid lumps in the material is needed to improve the quality of biological feed.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Fig. 1-Fig. 7, the utility model provides a kind of technical scheme:

Example 1:

A device for improving the quality of biological feed, comprising a hopper 1, a feeding cylinder 2, a screw conveying shaft 3, a horn cover 4, a horn sieve 5, and a power unit 6, the feeding cylinder 2 is vertically arranged, and the feeding cylinder 2 is A hollow cylindrical shell that penetrates up and down, the horn cover 4 is a horn-shaped housing, the horn screen 5 is a horn-shaped screen, the feeding port of the hopper 1 and the inlet of the upper end of the feeding tube 2 The feed port is connected, and the discharge port at the lower end of the feeding tube 2 is connected with the horn cover narrowing end 7 of the horn cover 4. The screw conveying shaft 3 vertically runs through the inside of the feeding tube 2 and the hopper 1, and the screw conveying shaft 3 The lower end of the horn screen 5 is connected with the horn screen narrowing end 9 of the horn screen 5, the horn cover 4 is above the horn screen 5, the taper of the horn cover 4 is smaller than the taper of the horn screen 5, and the inner angle ratio of the horn cover 4 bisects the cross section The inner angle of the horn screen 5 bisecting the cross section is small, as shown in Figure 1, Figure 3 and Figure 6; 0.3 cm.

Preferably, the power device 6 is a motor with a reducer.

Preferably, the screw conveying shaft 3 is a variable-pitch screw conveying shaft, and the pitch of the helical blades of the screw conveying shaft 3 increases sequentially from top to bottom.

The screw conveyor shaft 3 is a full surface screw conveyor shaft, and the screw conveyor shaft 3 is the same as the screw conveyor shaft in the full surface screw conveyor. The screw conveying shaft 3 is fixedly arranged inside the feeding tube 2 , and the screw feeding shaft 3 can rotate inside the feeding tube 2 .

The pitch of the helical blades of the screw conveying shaft 3 increases sequentially from top to bottom. Such setting can prevent special wet sticky materials from being subjected to greater mechanical extrusion in the feeding barrel 2, and keep the materials in a loose state.

The use operation method of the utility model:

Because the horn cover 4 is above the horn screen 5, the taper of the horn cover 4 is smaller than the taper of the horn screen 5, and the straight-line distance between the horn cover amplification end 8 of the horn cover 4 and the horn screen amplification end 10 of the horn screen 5 is 0.3 cm-1 cm, that is, the gap formed between the horn cover 4 and the horn screen 5 gradually decreases from top to small, an inverted wedge-shaped ring is formed between the horn cover 4 and the horn screen 5, the bottom of the horn cover 4 and the horn The lower part of the sieve 5 forms a very small gap, which can only allow powdery materials to pass through, and agglomerate materials cannot pass through.

Start the power unit 6, the power unit 6 is above the hopper 1, the power unit 6 drives the screw conveying shaft 3 to rotate, and the horn screen 5 at the lower end of the screw conveying shaft 3 also rotates synchronously with the screw conveying shaft 3.

During the production of biological feed, the wet material that has been inoculated in the mixer (the feed substrate and the microbial bacterial liquid are evenly mixed) is added to the hopper 1 of the utility model, and the material in the hopper 1 is affected by the screw conveying shaft 3. The material in the feeder evenly enters the feeding tube 2, and then the material enters the gap between the horn cover 4 and the horn screen 5 from the outlet at the lower part of the feeding tube 2. Since the gap formed between the horn cover 4 and the horn sieve 5 gradually decreases from top to bottom, a small gap is formed between the lower part of the horn cover 4 and the horn sieve 5, which can only allow powdery materials to pass through, and lump materials Can not pass through, powdery material can see through and fall from the sieve hole of horn sieve 5, and powdery powder can also form a very small gap from the bottom of horn cover 4 and the bottom of horn sieve 5 by falling.

If there are agglomerated materials in the material, the agglomerated materials will be broken up by friction in the gap formed between the horn cover 4 and the horn sieve 5. The lower part and the lower part of the trumpet sieve 5 form a small gap and drop through. The material also plays a role of material mixing during the process of being conveyed by the screw conveying shaft 3 and being dispersed in the gap between the horn cover 4 and the horn screen 5, and the material mixing is more uniform. Using the utility model to produce biological feed can avoid agglomerates in materials inoculated with microbial liquid, the materials can be mixed evenly, and the quality of feed can be significantly improved.

Embodiment 2: The difference from the above embodiment is: preferably, the linear distance L between the enlarged end 8 of the horn cover 4 and the enlarged end 10 of the horn screen 5 is 0.6 cm.
